No idea but try a third monitor and see which one it agrees with...I would trust coretemp as I have verified the accuracy of the displayed temps myself against the reported temps in the os and bios on my pc.

By the way....CoreTemp also runs x64 if you so desire (v99.8.0-64bit)

PC Probe temps are BIOS temps, i.e. both report readings from the same motherboard sensor. RealTemp/CoreTemp/SpeedFan temps are always higher, because they report readings from sensors within the CPU cores themselves.

I'm not familiar with either program, but I do know that with SpeedFan, it is easy to confuse the identity of the values, and display the graphics or system temps, thinking that they are the CPU.

Ok. So RealTemp is more accurate. So is 50c a better temp, sense it's coming from inside the CPU? Does it equate to 30c coming from the BIOS?

I can't speak for RealTemp, but CoreTemp doesn't report CPU temp, it reports the core temps, which are always lower than the CPU temp. SpeedFan reports both.

You mean higher temps right? Can't see the cores having a lower temp than the CPU, at least not yet.

As I said in a previous post, 50C is a bit high for idle(but not critical), depending on the ambient temperature. How hot does it get under full load?
For example, RealTemp reports both my CPU cores at 30C on idle, with the temp in my room at 23C; while under full load, the cores reach high 50's or rarely low 60's. That's quite good for an OC'd CPU, but it has an aftermarket heatsink/cooler, with correct TIM application & good case airflow.
When you changed your stock heatsink/cooler, which thermal compound did you use? Maybe there's too much or too little thermal compound(or a low quality one) between CPU & heatsink. Touch the heatsink(carefully) after the PC has been running for a couple of hours & see if it's hot/cool to the touch. If it's not hot/warm, it's either a badly seated heatsink/wrong TIM application. Try reseating the heatsink & correctly apply TIM and see if it makes a difference.

All that I can speak to is my experience, with my hardware, and the cores have always been cooler than the CPU temp. I imagine that is because the CPU temp is an accumulation of heat from all of the cores, while the cores are more independent.

Interesting. In my experience, the cores are always hotter than the CPU, since the cores produce the most heat and the CPU dissapates it via the heatsink & cooler.

Perhaps that is because you are running Intel, and I'm running AMD. It has been this way on all of my AMD rigs, as long as I can remember.
